Discard concave quads #71

Closed ayberkozgur closed 9 years ago

ayberkozgur commented 9 years ago

These kind of quads are frequently detected during tracking:

________        ________
\      /       |     _.´
 \    /        |   .´
  \  /         |  /
   \/          | /
   /\          |/
  /  \
 /    \
/______\

It is impossible for a tag to be concave from any perspective. It would be extremely cheap to calculate whether they are concave in order to discard them.

I actually have a PR ready for this that comes after the async stuff.
